[19] "Hey Boy" is a "euphoric",[18] "exuberant",[16] "flirty"[20] and "bouncy" pop and dancehall song,[21] in which, lyrically, Sia expresses a desire for male company.

[18][32] "Play Dumb", a song built around "vintage" synths and bass sounds,[27] is reminiscent of old-school hip hop and has G-funk-influenced production.

[19] "Beautiful Things Can Happen" is a piano ballad[33] produced by Labrinth,[18] and filled with Sia's signature vocal cracks.

[29] "Oblivion" features guest vocals from Labrinth,[35] and is a re-recorded version of the same song included on his 2019 album, Imagination & the Misfit Kid.

[1] Five[a] of the songs from the album appear on the film's soundtrack: "Together",[7] "Music",[48] "1+1",[49] "Beautiful Things Can Happen",[50] and, as the credits track, "Courage to Change".

[16] Writing for Associated Press, Mark Kennedy called the album "very, very good" and commented that songs on the record display some of the "most restrained and mature" songwriting Sia has ever done.

[17] The Evening Standard's David Smyth gave the album a rating of 3 out of 5 stars, and wrote that the songs' "melodies stick right away" and that there are "enough eccentric touches".

[33] Kitty Empire of The Observer gave the same rating, writing that the "sound design" on the album is "excellent throughout", but commenting that it would be easier to appreciate the songs without the controversy surrounding the film.

[62] Hilary Hughes of Entertainment Weekly criticized the album, writing that the lyrical theme of "motivational language" flies "dangerously close to inspiration porn".

[61] In RIFF Magazine, Domenic Strazzabosco wrote that Music "fails to strike a chord", commenting that Sia has compiled "a rather monotonous collection of songs" in the album.

[18] Keith Harris of Rolling Stone wrote that the album "lacks a big hit" to pull together a "competent level of craft".
